New Faculty Member

Dr. Linsey Marr will join the Environmental Engineering faculty at Virginia Tech after completing a one-year post-doctoral position in Earth and Planetary Sciences at MIT, working under Prof. Mario Molina, who won a Nobel Prize in Chemistry in 1995 for his work on the chemistry of the ozone hole. At MIT, her emphasis is on analyzing particulate polycyclic aromatic hydrocarbon (PAH) emissions and transformation in laboratory and field experiments. Dr. Marr received her Ph.D. in Environmental Engineering from UC Berkeley in May 2002. The title of her dissertation is Changes in ozone sensitivity to precursor emissions on diurnal, weekly, and decadal time scales and can be found on her current website www.mit.edu/~lmarr/


Awards/Honors/Recognition/Service

Dr. Marc Edwards was an invited speaker at the Gordon Research Conference on Aqueous Corrosion.

Dr. Bob Hoehn (professor emeritus) has been awarded the Abel Wolman Award for Excellence from the American Water Works Association (AWWA). The Wolman Award is the most prestigious award given annually by AWWA at its annual conference and exposition (held last week in New Orleans).

The specific citation for the award reads as follows:
"The Wolman Award is presented each year to an individual whose vision, creativity, and professional performance are characteristic of Abel Wolman’s long and productive career. This year, the Wolman Award goes to Robert C. Hoehn, Professor Emeritus, Civil Engineering Department, Virginia Tech, Blacksburg, Virginia, in commemoration of his considerable expertise as researcher, teacher, consultant, and mentor to many, and for his career-long energetic support of the water works community, just like Abel Wolman."

Bob is one of the world's experts on many issues related to drinking water treatment, especially in matters related to taste and odor control and lake/reservoir water quality management. His career accomplishments as an educator and researcher are many.

New Faculty Member

Dr. Peter Vikesland joined the Environmental Engineering Department at Virginia Tech after completing a postdoctoral fellowship in the Department of Geography and Environmental Engineering at Johns Hopkins University from 1999-2001. Dr. Vikesland obtained his Ph.D. at the University of Iowa in 1998 under the guidance of Dr. Richard Valentine. He has begun to develop a research program examining disinfectant interactions with drinking water distribution system components. Dr. Vikesland has eight years of experience examining monochloramine and free chlorine chemistry in drinking water. His work has focused on the decomposition reactions of monochloramine in the presence of oxidizable substrates (e.g., NOM and reduced iron).
